Detailed Description
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example one
The present embodiment provides a method for controlling a DPF to exit a regeneration prohibition mode, and fig. 1 is a flowchart of a method for controlling a DPF to exit a regeneration prohibition mode according to an exemplary embodiment of the present application, as shown in fig. 1, including the following steps:
s100: when the DPF is in the regeneration prohibition mode, the running information of the vehicle is obtained, and the running information of the vehicle comprises the vehicle speed information of the vehicle within a specified time length from the current time and the duration of the DPF in the regeneration prohibition mode.
S200: and judging whether the running information of the vehicle meets a preset condition or not, and controlling the DPF to exit the regeneration prohibiting mode when the running information of the vehicle meets the preset condition.
Before judging whether the running information of the vehicle meets the preset condition, the preset condition can be set according to the use scene of the vehicle, and the method specifically comprises the following steps: and setting a preset real-time vehicle speed threshold, a preset average vehicle speed threshold and a preset time threshold according to the use scene of the vehicle.
In S200, the preset condition includes at least one of: the vehicle speed information of the vehicle within a specified time from the current time meets a preset vehicle speed condition, and the duration of the DPF in the regeneration prohibition mode meets a preset time condition.
Through investigation, application scenarios requiring the DPF to be in the regeneration prohibition mode may include gas stations, enclosed spaces with combustible dust, fuel depots, and the like. These scenarios have a common feature: the speed at which the vehicle travels is significantly reduced relative to its speed on a normal road. Based on this, the vehicle running speed can be used as a condition for judging whether the vehicle needs to exit the DPF to prohibit regeneration. The device for controlling the DPF to exit the regeneration prohibition mode receives a vehicle speed signal of the vehicle in real time, and when the vehicle speed signal meets the vehicle speed limit value of the DPF exiting the regeneration prohibition mode, the DPF automatically exits the regeneration prohibition mode.
The vehicle speed information of the vehicle within a specified period from the current time may include a real-time vehicle speed and an average vehicle speed of the vehicle within a specified period from the current time.
Correspondingly, the vehicle speed information of the vehicle within a specified time length from the current time meets the preset vehicle speed condition, which may include: the real-time speed of the vehicle within a specified time from the current time meets a preset real-time speed condition, and/or the average speed of the vehicle within the specified time from the current time meets a preset average speed condition.
The real-time vehicle speed of the vehicle within the specified time length from the current time meets the preset real-time vehicle speed condition, and the method can include the following steps: the real-time speed of the vehicle within a specified time length from the current time is greater than or equal to a preset real-time speed threshold; the average speed of the vehicle within a specified time from the current time meets a preset average speed condition, which may include: and the average vehicle speed of the vehicle within a specified time length from the current time is greater than or equal to a preset average vehicle speed threshold value.
The duration that the DPF is in the regeneration inhibition mode satisfies a preset time condition, including: the duration that the DPF is in the regeneration disabled mode is greater than or equal to a preset time threshold.
After controlling the DPF to exit the regeneration prohibition mode, a prompt may also be sent that the DPF has exited the regeneration prohibition mode.
According to the method, after the vehicle speed limit value of the application scene is preset, the relation between the actual running vehicle speed of the vehicle and the vehicle speed limit value and the relation between the time of the DPF in the regeneration prohibition state and the preset time threshold value are compared to determine whether the DPF exits the regeneration prohibition state or not, so that the DPF automatically exits the regeneration prohibition state.
The method can avoid the problem of DPF blockage or damage caused by long-term regeneration prohibition of the DPF due to misoperation on the premise of meeting the requirement of a driver on using the regeneration prohibition function in a special scene, and is favorable for improving the vehicle operation reliability.
Example two
While the present embodiment provides an embodiment for controlling the DPF to exit the regeneration-prohibited mode, fig. 2 is a flowchart of a method for controlling the DPF to exit the regeneration-prohibited mode according to an embodiment of the present application.
The present system involves the following 4 devices: an Engine Control Module (ECM), a vehicle speed gauge, a CAN bus, and a DPF regeneration disable switch.
In the normal running process of the vehicle, the vehicle instrument sends the vehicle speed information to the engine ECM through the CAN bus in real time, and the ECM receives the vehicle speed of the instrument in real time and performs timing, calculation and comparison.
When the vehicle runs to a gas station, a high-dust area, an oil depot and other spaces containing inflammable matters, a driver can actively press a DPF regeneration prohibition switch to prevent high-temperature exhaust generated by DPF regeneration from igniting the inflammable matters in the air to cause accidents. When the vehicle leaves the dangerous area, the driver should turn off the DPF regeneration prohibiting function to make the vehicle run normally.
However, in an actual use process, there is a case where, after the DPF regeneration prohibition function is activated by the driver, an operation of canceling the DPF regeneration prohibition is not performed when the vehicle is driven out of the dangerous area, so that the DPF is in a regeneration prohibition state for a long time, and the DPF is clogged and deactivated, which affects the vehicle operation; in another situation, when a new product and a new function are in the initial stage of the market, a driver does not know the functions of the vehicle and the switch, and the DPF is in a regeneration prohibition state for a long time due to misoperation, so that the DPF is blocked and loses effectiveness, the vehicle operation is influenced, and bad use experience is brought to a vehicle owner.
In order to solve the above problem, by performing investigation and analysis on different usage scenarios, a vehicle speed limit and a time limit of the DPF in the regeneration prohibition state, which are applicable to the usage scenarios, are determined according to the usage scenarios of the vehicle, and the vehicle speed limit and the time limit of the DPF in the regeneration prohibition state may be different in the different usage scenarios. The vehicle speed limits may include, among other things, a real-time vehicle speed limit and an average vehicle speed limit.
When the real-time running speed of the vehicle is greater than the set real-time vehicle speed limit value within a specific time, and/or when the average vehicle speed of the vehicle within the specific time is greater than the set average vehicle speed limit value, and/or the duration of the DPF in the regeneration prohibition state reaches the set time limit, the ECM controls the DPF to automatically exit the regeneration prohibition function and enter a normal DPF regeneration state to ensure the normal work of the DPF, so that the damage of the DPF caused by long-term prohibition of regeneration is avoided. The set real-time vehicle speed limit value and/or the set average vehicle speed limit value can be modified according to needs, and can be set to any value of 0-70 km/h, for example.
When the DPF exits the regeneration prohibiting function, the ECM sends a message notice that the DPF has exited the regeneration prohibiting function, and the instrument displays that the DPF has exited the regeneration prohibiting state to remind a driver.
EXAMPLE III
A system for controlling a DPF to exit a regeneration prohibition mode includes a CAN bus, a DPF regeneration prohibition switch, and an engine ECM and a memory, and when the engine ECM runs program codes stored in the memory, running information of a vehicle is acquired from the CAN bus, and whether the DPF regeneration prohibition switch is turned off or not is controlled by executing the method for controlling the DPF to exit the regeneration prohibition mode as above.
